'1. Application filed Sentember 521, 1886. Seria T all whom it malyconcern:

Be it known that I, CLEMENT B. BIsHoP, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Spectacles and Eyeglasses,

of which the following is a specification.

My inveution consists of certain improvements in the construction ofspectacles, designed more particularly for facilitating and rceconomizing their manufacture.

In the accompanying drawings, Figure 1 is aperspective view ofa pair ofspectacles,illustrating one of the features of niy invention, thetemples being broken off. Fig. 2 is a view of a modification. Fig. 3 isan enlarged perspective view illnstrating the construction of the endpieces. Fig. 4 is a view illustrating the mode of prodncing half of oneof the end pieces. Fig. 5 is a perspective view, also drawn to anenlarged scale, of the end of one of the temples.` Fig. 6 is a sectionalview of the same, illnstrating its position in the end piece. Fig. 7illustrates a modification of the same.

In the manufacture of spectacles one of the chief elements of expense isthe filing which has to be done on the different parts, and moreparticularly the end pieces.which are attached to the ends of the rims.The punching out of these end pieces leaves sharp corners, which have tobe filed down.

It is one of the objects of my invention to so const-ruct the end piecesas to dispense with this filing so far as possible.

It is a further object of my inventon, in applying it to rolled platedspectacles, to produce an article in which all the exposed parts shallbe plated.

Heretofore. so far as I am aware, it has been 40 found impossible toproduce plated spectacles without leaving some exposed part withoutplating, and more partieularly the edgcs of the end pieces to which thetemples are connected.

I attain these objects-that is, I dispense with the filing of the endpieces, and when making plated work produce end pieces with all theexposed parts plated, by striking these.

end pieces np With rounded surfaces, as shown in Figs. 1, 2, and 3. i

'0. 214,130. (No model.)

Referring to Figs. 1 and 2, A A are the usual rims of the spectacles,split at one end, a, to which the two halves of the end pieces B aresoldered, the two halves of these end pieces being of such a Characterthat they can be united or fastened together by means of a small screw,which thus secures the ends of each rim. I form these end pieces B oftwo halves, b b', Fig. 3, WhichI strike up With rounding surfaces bymeans of a punch 'and die, as illustrated in Fig. 4, so that when thetwo are united by means of the screw d, Fig. 3, they form an end pieceof a rounded or substantially spherical form. As a general rule, the endpiece will be in the shape of a fiattened sphcre or ovoid; but I do notlimit myself to any precise shape, so long as each half is struck upwith a rounding surface to avoid corners, which might need filing.

In using plated stock to form the end pieces this method 'of striking upthe halves With rounded surfaces enables nie to leave a plating over theentire surface, as Will be understood on reference to Fig. 4, where thedark line o indicates the plating. piece such vas described, whethermade of steel or of plated stock, can be readily distinguished from onewhich has been shapedi by the old filing process, owing to theappearance given to the article by the Shaping-die in striking' up theend piece. Such appearance will be best understood by. those skilled inthe art vby the use of the descriptive phrase struek up), The adjoiningflat faces of the two halves of the end pieces are milled out in anydesired way or by any desir'ed means for the reception of the flattenedends of the temples',or the necessary recesses may be formed in the twoA struck-up end ssi halves of the end pieces in the punching opera- Inorder to get a sufficient frictional contact between the flattened endof the tempie and the two halves of the end piece, I split the flattenedend c of the tempie E at an angle, as illnstrated in Fig. 5, and bendthe two split ends slightly apart, so as to form a species ofspring,which,when the tempie endy is inserted between the ends b and b',is compressed by the latter.

To form a stop to prevent the tempie E from being turned beyondtheposition at right angles to the glasses, the milled-ont portion ofone or both of the half end pieces, Z) b', may, as shown in Fig. 3, beprovided with a straight portion, f, against which the correspondingstraight portion on the eye e of the tempie bears when turned out to theposition at right angles to said glasses, as illnstrated in Fig. 6; orcorresponding shouldersf' may be formed on the end piece or pieces andthe eye of the temple, as illustrated in Fig. 7.

Eyeglasses have heretofore been made with rounded end pieces on therims; bnt,so far as Iam aware, in all such cases such ronnding has beenproduced by the tedious filing process solely for the purpose of neaterfinish in the more expensive grades of these eyeglasses. In myspeetacles and eyeglasses the end pieces are punched np in a ronndingform, and this punehing up of the end pieces in ronnding form has thespecific mechanical pnrpose of thereby dispensing with the expensive andtedions filing heretofore necessary.

I elaim as my invention- 1. A spectaeie-rim having end pieces withstruck-up ronnded surfaces, snbstantially and for the purpose described.

2. The combination of the end pieces of a pair of specfacles withteinples having eyes e, split substantially as described.r

In testimony whereof I have signed my name to this specification in thepresence of two snbscribing witnesses.
